Question: is close button for JTabbedPane available?

[Gaulm]

As the title says I'm wondering if there is a function or property to display a close button near the title of a tabbed pane, like the one Intellij uses when you open many files.
It would be nice to have so that we don't have to deal with different LaFs.

No, this is not yet implemented. Maybe in the future...

You could try following:

JPanel tab = new JPanel( new BorderLayout( 5, 0 ) );
tab.setOpaque( false );

JButton closeButton = new JButton( new FlatInternalFrameCloseIcon() );
closeButton.setContentAreaFilled( false );
closeButton.setBorder( null );
//TODO add action listener
tab.add( closeButton, BorderLayout.EAST );

tab.add( new JLabel( "Tab Title" ), BorderLayout.CENTER );

tabbedPane1.setTabComponentAt( 0, tab );

You could also try JideTabbedPane from JIDE Common Layer, which is supported by FlatLaf: https://github.com/JFormDesigner/FlatLaf/tree/master/flatlaf-jide-oss

I came across a similar need, and tried out your suggestion above. It worked very nicely in my case:

The only tweek I made was to set the max size of the button:

JButton closeButton = new JButton(new FlatInternalFrameCloseIcon());
closeButton.addMouseListener(new CloseListener(tab));
closeButton.setPreferredSize(new Dimension(16, 16));
closeButton.setMaximumSize(new Dimension(16, 16));
closeButton.setContentAreaFilled(false);
closeButton.setBorder(null);

Thank you!
